Updating a previous report, Los Angeles Chargers LB Denzel Perryman (ankle) may need surgery on his injured ankle and will miss at least the first four games of the regular season, according to a source.

Fantasy Tip: Oliver probably would only see limited touches if he is the primary backup this season but could still be used out of the backfield as a receiver. He could be a late-round option in deeper leagues as a handcuff to Melvin Gordon but can be avoided in most leagues.

Fantasy Tip: Allen missed a few days of practice because of a sore calf but is back on the field and should be fine moving forward. He has dealt with injuries over the last few years but is one of the better receivers in the league when he is healthy. Owners could select Allen as their No. 2 receiver in drafts if he stays healthy.
